Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

We’ve all heard linear motors, like those propelling Maglev trains, described as “unrolled” versions of regular electric motors. The analogy is apt and helps to understand how a linear motor works, ...

Stepper motors are fascinating and incredibly important to having automation or robotics in the here and now. The precise terms of their name refer to how they work that is; a motor will turn one step ...

The project illustrates the use of a PIC microcontroller in creating the stepper motor controller by sequencing the steps, along the with TIP120 Darlington pairs for the switching circuitry, and a ...

Here is how to implement a stepper motor to sense position and actively correct any error that might accrue during actuation.

It’s increasingly common for designers to pair stepper motors with motion-control SoCs. In fact, more design engineers than ever are setting up SoCs themselves for motion applications. These chips ...

Few hackers have trouble understanding basic electric motors. We’ve all taken apart something that has a permanent magnet DC motor in it and hooked up its two leads to a battery to make it spin.
